  1. 化学平衡常数

  2. 复习： 1、化学平衡状态？ 2、化学平衡的特点？ 3、化学平衡的标志？

  3. 1、化学平衡常数： 2、数学表达式： 3、意义： （1）不随浓度改变而变，只与温度有关。 （2）推断反应进行的程度。（107、10－7）

  4. 化学平衡常数的书写： 1、如果反应中有固体或纯液体参加 CaCO3(s) = CaO(s) + CO2(g) C(s) + H2O(g) = CO(g) + H2(g) 注意物质的状态 2、稀溶液中有水参加反应 Cl2 + H2O = HCl + HClO 3、同一可逆反应，可以用不同的化学方程式表示 N2O4(g) = 2NO2(g) 2NO2(g) = N2O4(g)
